Exhibit 4-2 Consider mixing an aqueous solution of FeCl₃ with an aqueous solution of KOH:
FeCl₃ (aq) + KOH (aq) →??
Refer to Exhibit 4-2. What is the overall equation for the precipitation reaction that ensues?

Question

Quizplus · Accepted Answer

When aqueous solutions of FeCl3 and KOH are mixed, they react to form solid Fe(OH)3 and aqueous KCl. The balanced equation for the reaction is:

FeCl3 (aq) + 3 KOH (aq) → Fe(OH)3 (s) + 3 KCl (aq)

Note that the subscript "3" after Fe and Cl denotes the number of atoms of each element present in the compound. Similarly, the subscript "1" after OH denotes that there is only one hydroxide ion in the compound.
